I remember doing one shop in probably 1996...I got a phone call, then had to send the form in. I don't remember how I found it now, but it must have been something in print.
I remember it didn't pay well, and I wasn't too happy with the whole process. Gave it up in '96 after that shop.
Couple years later, the internet was more in use and I started back up with several companies, and I think most had online forms. But I do remember one company I shopped with regularly in 1998 and I faxed the hand written form in, even though I got my assignments by email.
Still a lot of calls at that time, 98-2001...after 2001 I took some time off from it, and now that I'm back about three years...I very, very rarely speak to anyone on the phone, compared to all the time in '98...
